REVERSIBLE WINDOVT-SASH.

Specification of Letters Patent.

Patented Feb. 29, 1916.

Application filed February 24, 1912. Serial No. 679,743.

To all whom it may concern: j Be it-known that i, STEPHEN Vinson, a resident of Swissvale, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Reversible lVindow-Sashes, of which the following is a specification.

This invention relates to window construction and more particularly to sliding and swinging sash windows.

The objects of the invention are to provide in connection with a sliding sash window, an improved construction and arrange ment of parts which will permit the sash to swing about a horizontal axis without manipulation of any of the fixed parts of the window frame, to permit access to the outer surface of the sash from the inside; to provide an improved construction in which the sash may be swung or reversed in position only when brought to a definite position in the window frame and inwhich, when tilted or swung either out of, or into normal position, it is properly alined with the frame during such movement and swings without friction with, or rubbing or marring of the window frame.

The invention comprises the construction and arrangement of parts hereinafter de scribed and claimed.

In the drawings, Figure l is an elevation from the inside, of a window constructed according to my invention; Fig. 2 is an elevation of the stile shown at the right in Fig. l, the sash being indicated in normal position in full lines and in reversed position in dotted lines; Fig. 3 is a cross section through the frame stile, on the line 3-3 Fig. 2, and sashes being indicated on dotted lines; Fig. 4 is a detail view corresponding to Fig. 2, of the abutment mechanism; 5 is a detailed elevation, partially in section, of the mechanism shown in Fig. 4; Fig. 6 is an elevation of another part of the mechanism shown in Fig. 4; Fig. 7 is a detailed view of-a looking or retaining bolt; and Figs. 8 and 9 are respectively front and side elevations of the sash pivot and the flexible supporting means connected thereto.

The present invention is in the nature of an improvement upon the invention described, shown and claimed in my prior application. Serial No. 674,447, filed Januar v.31st,1912. In t he embedilnentslr'own in the draw ings, the invention is applied only to the lower or inner sash. Obviously, however, it may be applied with equal facility to the outer or upper sash, and it is to be understood that the invention is not confined to the particular embodiment shown.

, The window illustrated in the drawings comprises the usual horizontal sill l, vertical side members 2, and the horizontal head, not shown. The side members 2 are of similar construction, but reversed or inverted, as is obvious, and only one thereof will therefore be described. Fig. 3 shows in cross section the member 2 at the right in Fig. 1. It comprises a pulley stile 4, which forms the inward face of the usual weight box or frame, the other members of which are not shown. Stile 4 is preferably pro vided with an inwardly facing shoulder 5 against which rests the outer face 6 of the lower and inner sash 7, and which may either be an integral portion of the pulley stile 4 or a separate piece attached thereto. To retain this sash in upright position in the frame a vertical inner stop 8 is provided on the face of the stile 4. This stop extends vertically for the full length of the frame. and, with the shoulder 5, forms a groove, guide or runway 9. As illustrated in Fig. 3, the sash 7 is provided with suitable projections or pivots 17 sliding in the grooves or guideways 9 and engaged behind stop 8 to hold the sash in the frame. The sash 7 is fitted to the frame and against the shoulders 5 by the horizontal adjust ment of the stop 8 thereon, and against the projections of the sash.

In the present construction the sash 7 is arranged to turn or swing about the projections or pivots which are fixed thereto and also form connection between the sash and its cords or other flexible supporting means. The sash is shown as provided at each lower corner with a socket 1:") in which is seated the stem 10 of the pivot or projection referred to and comprising a cylinder of steel or other metal. having a projecting end 17 provided with an annular groove 18 therein. To secure the pivots in their sockets, they are provided with transverse holes or apertures 19 through which suitable securing screws 20 are passed into the body of the sash. The projecting ends I? form the pivots about which the sash turns and also a m eans forconnection tothe sash of the flexible supports 21 on which the sash is hung. These flexible supports are shown as cords, but may consist of a chain or other means. When the flexible supporting means consist of cord or other similar material, connection to the pivots 17 is made by turning or folding the cord upon itself to form a loop 22 held together by a suitable metal clip 23, and through which loop is passed one turn of an S-shaped hook 24, formed of wire, the other turn of which is seated in the annular groove '18 in the pivot 17. WVith' the sash hung on a chain, the upper turn of S-shaped wire 24 is simply hooked into the last link of the chain in an obvious manner. Although only one of the pivots and its connection to the supporting means is shown in the drawings, it will be understood that such pivots and connections are provided at both of the lower corners of the'sash. The flexible supporting means or cords 21 travel in the runways or grooves 9 behind the stops 8, and as is usual, are passed over the pulleys, not shown, at the upper ends of the pulley stile and connected at their other ends to ordinary counter-weights.

To keep the lower sash in its normal upright position, it is provided with suitable bolts, arranged to be engaged with and dis engaged from the stiles to prevent or allow rotation of the sash. These may be of any preferred construction, for example, that shown in my prior application 674,447, referred to. or as illustrated in Fig. 7. As shown, bolt 30 comprises a pin or bar seated in a bore 31 in the side stile of the sash and normally held projected therefrom by a spiral c mpression spring 32 seated in the bore 31 behind the bolt. To retract the bolts when desired, they are provided with lat-v erally extending handles or knobs 33 projecting through and slidable in slots or apertures 34 in the inner face of the sash stiles, as shown in Figs. 1 and 7. The slots or apertures 34 are preferably made .of such length and are so located in the sash that normally the bolts are projected by the.

springs into locking engagement with the side frames of the window and when withdrawn to their full extent, their ends are flush with the side faces of the sash. In the particular embodiment shown the pin or bar forming the bolt is provided with a cutaway portion or notch 35 and normally embraces a rib or bead 36 on the stop 8. This is suitably formed by undercutting a portion of the back face of the stop 8, as at 37 and notches or pockets 38 are formed in the ribs or beads 36 to enable the bolts 30 to be withdrawn therefrom when reversal of the window is desired. One of the bolts 30 is mounted upon each of the side stiles of the sash, as shown in Fig. 1. Preferably, the bol s '3 are f rmed w th b a d or inclined ends "12 to enable them "to push the sash cords or other supporting means out of the way when the bolts are projected into grooves 9.

As stated, the sash reverses or swings only when brought to a particular position, this being indicated in dotted lines in Fig. 2. To properly stop or locate the sash in this position and hold it during swinging or reversal I provide the improved mechanism shown in Figs. 3, 4, 5 and 6. This comprises a suitable abutment or stop which is movable into and out of the path of movement of the projections or pivots 17 along the guides, grooves or runways 9, and against which the pivots rest during swinging motion of the sash. In the particular embodiment shown the mechanism comprises a base or plate 40 suitably secured to the inwardly facing shoulder 5 of the stile 4, as by screws 41, and provided with a flange 42 projecting forwardly into the groove or runway 9 and the edge 42 of which forms a retainer to confine the pivot 17 during the reversing movement of the sash. This flange may be formed by slotting the base plate 40 and turning a portion thereof inwardly, as shown. Pivotally connected at 43 to the upper portion of the flange 42 is an abutment or stop 43 the lower end of which is beveled off, as at 44, in such manner that its edge is horizontal when projected into the grooveor guideway. To move the abutment or stop 43, a link 45 is provided, formed of a bar of metal pivotally connected at 46 to the lower end of the abutment 43 and extending through a slot or aperture betweenthe stop 8 and stile 4. Preferably this slct is formed by cutting away a portion of the back of the stop 8, as shown. A suitable finger lever 47 is pivotally mounted on the inner face of the stile 4 upon a. screw 48 which is turned in tightly enough to frictionally hold the finger lever 47 in position. As shown, the

finger lever 47 has an inturned lower end 49 to space the same away from the inner face of the stile 4, and is provided with a thumb piece 50 for operation thereof.

In the drawings, I have illustrated in detail the abutment mechanism mounted upon the side member 2 of the frame at the right in Fig. 1. It is, however, to be understood that similar mechanism, reversed or inverted in .construction and arrangement, is also provided on the side member 2 at the left in Fig. 1, and the finger lever 47 of such mechanism is indicated in Fig. 1.

The operation of my improved window will readily be understood from the foregoing description, taken in conjunction with the accompanying drawings.

The lower sash having been insertedinto position in the frame, maybe moved up and down along the guideways or grooves at *will, To, tilt, swing, or reverse the sash into position for cleaning the outer surface thereof, it is moved down in the frame until its pivots 17 are substantially below the position of the abutments 43. These have previously been placed in position on the frame of the window and properly spaced exactly the same distance from the lower member 1 thereof on opposite sides of the window. The thumb members 50 of the abutment mechanisms are now grasped and the finger levers 47 oscillated about their pivots 48 to oscillate the abutments or stops 43 about their pivots 43*. This moves each abutment 43 to the position shown in full lines, Fig. 4, from that shown in dot and dash lines. The window is now moved upwardly until its pivots abut against the lower edges 44 of the abutment members. The handles 33 of the retaining bolts 30 on opposite stiles of the window sash are now grasped and the bolts withdrawn from the notches 38 provided in the ribs or beads 36 of stops 8. These notches are of course spaced the requisite distance from abutments 43. The sash may now be swung or reversed into position shown in dotted lines, Fig. 2. As the sash swings gradually down into horizontal position the upward pull on its lower edge exerted by the counter-weights and supporting means 21 keeps the pivots 17 closely confined between the stops 8, guiding edges 42 of flanges 42, and the lower edge 44 of the abutment 43. The sash consequently turns about the centers of the pivots 17 as an axis. The sash is brought back to normal position by grasping the upper rail thereof and swinging it upwardly, with the bolts 30 withdrawn into the sash. After the sash has been fully folded against the shoulders 5, the bolts 30 are allowed to slide out through the cutaway portions or notches 38 in ribs 36 and thus come into engagement with stops 8. The abutments 43 are next withdrawn from the path of movement of the pivots 17 by reversed operation of the finger levers 47. The sash may now be moved up and down at will. The inner edges 42 of the flanges 42, as stated, confine the pivots 17 very closely in position as the sash turns. This prevents the lower and outer edge of the sash during every stage of its movement from binding in the frame or from marring or otherwise injuring the painted surfaces of shoulders 5. Furthermore, by positioning the abutment mechanisms at tl 1e same height above the lower member or sill 1 of the frame, the sash is always properly alined during its reversing movement and will swing in and out of the frame without binding or friction or injury to its painted surfaces. To assist in properly locating these abutment members, suitable positioning means are provided upon the base plates 40 for temporarily holding them during final securement. In the embodiment shown this comprises a pair of small apertures or holes 51 through the ends of the plate. In assembling the mechanism in the frame the carpenter spaces off the proper distance from the bottom of the frame for location of the abutment members. One of these is then held in proper position and a brad, small nail or tack is driven through each of the apertures 51. This temporarily holds the base plate 40 in position and prevents alteration of its position during the final securement with the screws 41 to the frame.

hat I claim is:

1. In a construction of the character described, the combination of a frame having side stiles provided with grooves, a sash slidable between said stiles and having pivots traveling along said grooves, and abutments for cooperation with said pivots and comprising a base secured to the frame and provided with a plate, one edge of which is arranged to cooperate with said pivot, an abutment member pivoted to said base, and means for moving said abutment member into the path of movement of the pivot.

2. In a construction of the character described, the coinbination of a frame having side stiles provided with stops and inwardly extending shoulders forming grooves, a sash slidable between said stiles and having pivots traveling in said grooves, means movable into the paths of movement of said pivots to form abutments therefor, said stops being provided with ribs, and adjustable locking bolts on said sash having cutaway portions embracing said ribs and adapted to be withdrawn from said grooves through notches in said ribs.

In testimony whereof, I have hereunto set my hand.
